title: 8-{(E)-[(4-Chloro-phen-yl)imino]-meth-yl}-1,1,7,7-tetra-methyl-1,2,3,5,6,7-hexa-hydro-pyrido[3,2,1-ij]quinolin-9-ol.
abstract: The title Schiff base, C23H27ClN2O adopts the phenol-imine tautomeric form, with an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring motif. Three C atoms of the heterocyclic moiety of the hexa-hydro-pyrido-quinoline unit, as well as the two methyl groups bonded to one of these C atoms, are disordered over two set of sites, with anoccupancy ratio of 0.740 (4):0.260 (4).
